Purring like a kitten with my class 10(claims to get 40MB/s)128GB card from sony. You just have to download the driver(installs when you put in the card), and format the card from within the device itself.

Out of the box running 10.3, the Passport had no problem with my 64GB SanDisk Extreme Pro micoSD card. I'm now running 10.3.1.1151 and it also has no problem with the card, but I'm really wishing there was a ringtone folder like old times.....

I see that it comes with 32 but want to make sure I can get 64 into it. Thanks.

When I got my passport I was going to get a 64, but thought about it and I think going right to the 128 is a better option,why pay twice? even though I probably don't need all that storage.so when the day comes and my 32 is not enough I'll jump right up to the 128.

Looks like you and I have something in common. 32 gigs is good enough for now but, if I ever get around to organizing my music one day, I'll make the jump right to 128 too.
